OK, I'm imagining it in a camera phone… small displays in all camera phones, right? This invention would change *that* how? Small keyboards in all camera phones, too, right? Being able to jump to a specific website from a picture is neat, but what about typing anything else in? This invention would change *that* how? Pardon my obtusuosity; maybe you'll have to draw me a picture…

Actually, this is an old idea and there has been a lot of progress in the market. Shazam has been doing something very similar for a while now for music. http://shazam.com/uk/do/home Basically you hear a song you like, you call a service and hold up your cell phone. Instantly you're SMS'd the song title, etc, and an option to buy. Works GREAT. Fido now offer thier service in Canada. Neat stuff.

I really think the ability to effortleslly link stuff in the real world to the web is a key enabler of e-commerce beyond the PC. When I can point a camera, or a Shazam enabled phone, at some arbitrary object, and instantly get back info about it, I think the way I use the web will change dramatically.
